Well for a start, you are using the ~ character which indicates the root directory of the application.

Since you are saying that the image is in C:\\Search\\Searchdoc\\Documents\\ then that won't be found, since your code is actually looking in projectRoot\\Search\\Searchdoc\\Documents

As for how to get this image to show in a webpage, it won't simply work for accessing it from the C drive. IIS will not serve images that aren't in the web site folder structure. I would suggest moving it into the website.

If you need to keep it stored in a folder outside your website, you would need to look at streaming it, or using a sort of proxy page. Have a look at the answer here: How to display image which is stored in local drive? to get an idea of the proxy method
